The nine-pointed star symbolizes the nine fruits of the Holy Spirit listed in the Epistle to the Galatians.
This star is sometimes shown with the Latin initials for each of the fruits (charitas, gaudium, pax, longanimitas, benignitas, bonitus, fides, mansuetudo and continentia) placed within the points.
The nine-pointed star is also the symbol of the Baha'i Faith.
